COP-TUBE MACHINE.

SPECIFICATION forming part of Letters Patent No. 373,566, dated November 22, 1887.

(No model.)

IO with the accompanying drawings, is a specification.

This invention relates to improvements in machines for making spirallywound paper cop-tubes of the kind used for spinning copyarn onmule-spindles, and it is carried out as follows, reference being had to the accompanying drawings, wherein Figure 1 represents a .plan view of the machine. Fig. 2 represents a front elevation of it. Fig. 3 represents an end view, seen from w in Fig. 2, showing in section the paste-re ceptacle. Fig. irepresents a cross-section on the line A B, shown in Fig. 1. Fig. 5 repre sents a section of the shipper device on the Figs. 7 and 8 represent, in enlarged side View and longitudi nal section, the kind of cop-tube that the machine is designed to produce; and Fig. 6 represents a plan of the paper strip from which 0 the cop-tube is made.

chine, the lower ends of which are secured in a suitable manner to the base or table-top Z1, as shown.

0 is the driving-shaft, located in bearings in the frames a a and provided with fast and loose pulleys c c, by means of which and a strap or belt from a rotary drivingpulley a rotary motion is imparted to said drivingshaft 0.

c is a brake drum or wheel secured to the 5 driving-shaft c, which may be provided with a suitable brake-shoe, if so desired, for stopping the machine when the belt is shipped from the fast to the loose pulley on the driving-shaft; but this is not essential.

On the driving-shaft c is secured the gearpinion c, the teeth of which mesh in the teeth of the intermediate pinion, d, located on the shaft (1. The teeth of the intermediate pinion, (1, mesh in the teeth of the gear-wheel e,

secured to the shaft 0, said shaft having se- To the driving-shaft c is secured the gearwheel 0 the teeth of which mesh in the teeth of the pinion f, secured to the cop-tube shaft f, that is journaled in hearings in the frames a a, and by this means a quick rotary motion is imparted to said shaftf. of the shaftf, outside of the frame a, is made slightly tapering, as shown at f in Figs. 1 and 2, and upon it is wound the strip of paper F, Fig. 6, for forming thetapering tube F. (Shown in Figs. 7 and 8.)

g is a rock-shaft located in bearings in the frames at a, and it has secured to it the lever g, the outer end of which is pivoted to a link, 9, having its lower end hinged to a vertically- The forward end 6 movable post or rod, G. The post G, link and lever g are normally held in the positions shown in Fig. 4 while the cop-tube is being made by the influence of the spring G, one end of which is connected to the bar G or a projection thereon, and having its other end may be used for the purpose of automatically 3 raising the post G without departing from the spirit of our invention.

a is a stationary bar or projection secured to frames a a, or either of them, and said pro- "ection a serves as a sto to limit the u ward o J P 9 motion of the lever g, the link 9, and rod G, as shown in Fig. 4.

To the rock-shaft g is secured the arm or lever h, having looselyjournaled on a pin in its upper end the belt-carrying roller h, from which leads to the roller 6 the endless pastecarrying belt or band H, that may be made of rubber or other suitable elastic or inelastic materiahas may be desired. During the operation of forming the cop-tube the said endless band H is held taut against the cop-tube spindlef by the influence of the spring G and the connecting mechanism to the arm h, as above described. When the cop-tube is finished, the rod G is depressed by means of a treadle of any ordinary construction, such treadle being, however, not shown in the drawings, and when such rod G is depressed against the influence of the spring or weight G the shaft 9 is rocked, causing the lever hto move in the direction shown by arrow in Fig. 3, thus withdrawing the endless band H from the coptube spindle f, to permit the finished coptube to be thrown off from said spindlef.

For the purpose of automatically starting and stopping the machine we employ the following inechanism: To the vertically-adjust able rod G is secured the wedge or cam G (shown in Fig. 5,) which, as it moves upward with the rod G,.forces a shipper-bar, i, to the position as shown in Figs. 1 and 5, and thereby ships the driving-belt onto the fast pulley c by means of the prongs t" i, secured to said shipper-bar. The shipperbar t is guided in one end through a perforation in the frame a and in its other end in a perforation in a post or bearing, 1), secured to base I), or in any other suitable or equivalent manner. When the rod G is forced downward after the coptube is finished, the shipper-bar z is automatically moved toward the left in Fig. 5 by the influence of a spring, I, one end of which is secured to the shipper-bar t and the other end secured to the frame a, or any other stationary part of the machine, causing the prongs t" i to ship the driving-beltfrom the fast to the loose pulley c and thereby stopping the machine.

In connection with the cop tube spindlef we use an automatic device for knocking off the cop-tube, when finished, from said spindle, and this is carried outas follows: In guides in the frames at a is arranged the bark, that is normally held in the position shown in Figs. 1 and 2 by the influence of a spring, secured in one end to said bar 70 or a projection thereon, and in its other end to a post or rod, 70', secured to the base I); or, if so desired, any other or equivalent spring or weight may be used for this purpose.

To the forward end of the sliding bark is secured or made in one piece the arm or bracket is, the rear end of which is perforated to allow it to slide longitudinally on the cop-tube spindle f,that passes through such perforated end of the arm 70 It will thus be seen that the cop-tube may be thrown off from the spindle f by moving the bar 7c and its arm 70 toward the left, as shown in Fig. 1.

7c" is a guide-pin secured to the throw-off arm it over which the paper strip is guided to the spindle f during the making of the cop-tube.

k is a gage made adjustable .on the pin 76 for the purpose of guiding the paper strip properly to the spindlef in s arting the making of the cop-tube.

The cop-tube is automatically thrown off the spindlef by connecting mechanism from the rock-shaft g and treadle-bar ,G when the machine is stopped, as follows: On the rock-shaft g is secured the lever or arm 9*, (shown in Figs. 1, 2, and 4,) which, when the bar G is depressed, come in contact with thelowerleg ofthe bell-crank lever Z,pivoted on the fulcrumpin Z, and causes the upper leg of such bellcrank lever to actuate a pin or projection, 70 secured to the throw-off bar 70, and thus to move the latter toward the left against the in fluence of the spring or weight 70.

k in Fig. 2 is a spring secured to the pin or the bar 70, and having its free end pressing on the upper leg of the bell-crank lever Z, for holding the latter in contact with said pin on the bar It as the latter is reciprocated; but

this is not essential, as another pin secured to the bar is may serve the same purpose.

The operation of our improved machine is as follows: By relieving the downward press: are on the rod G the spring G raises the lever y to the position shown in Fig. 4 at the same time as the bar It is drawn backward by its spring 70' to the position shown in Fig. l, and the shipper-bar 2' moved by the cam or incline G to the position shown in Figs. 1 and 5, causing the driver-belt to be shipped on the pulley c, by whicha quick rotary motion is imparted to the cop-tube spindlef and a slower rotary motion imparted to the pasteroller 0', causing the endless belt H to be set in motion and to be held against the cop-tube spindlef with a proper pressure during the travel of said endless belt. A proper amount of paste or other suitable adhesive material is thus taken from the paste-trough E to the traveling belt H. A. strip of paper, F, Fig. 6, is then taken by the operator, and its forward end, F, introduced between the under side of the rotating spindlef and the paste carrying band H, causing the strip to be pasted. and'wound spirally on said spindlef, the operator meanwhile guiding the strip, as shown in dotted lines in Fig. 3-that is, holding it with a proper tension against the guiderod 76 and up to the gage 70 as shown in dotted lines in Figs. 1 and 3. After the whole length of the paper strip has been wound on the spindlef, an internally and externally tapering cop-tube, F, is produced, as shown in enlarged views in Figs. 7 and 8. By depressing the rod G against the influence of its spring G the cam or incline is released from the shipperrod t, and the latter is carried inward by the influence of its spring I sufficiently to ship the driving-belt onto the loose pulley c", causing the spindlef and the pastecarrying belt and its rollers to stop, the belt H to be withdrawn from contact with the spindlef, and the throw-off arm 70 and its bar 70 to be moved against the influence of the spring k toward theleft, and'thereby causing the piece k toforce the finished cop-tube from the spindlef, when it may be picked up by the operator and placed on a drying-rack or otherwise disposed of, as may be desired. Af ter one cop-tube has been thrown ofl' from the spindle f, the operator releases the rod G, causing the machine to be again set in operation, a second strip of paper is guided onto the spindlef, and so on.

Having thus fully described the nature, construction, and operation of our invention, we wish to secure by Letters Patent and claini 1. In a cop-tube machine, the rotary spindlef",and the endless paste-distributing band H and intermediate connecting mechanism, substantially as described, to the d rivingshaft a, combined with the automatic belt-shipper device, consisting of thespring-pressed rod (i, the cam or incline G, secured to it, and the shipper-bar z, with its spring I, substantially as and for the purpose set forth.

2. In a cop-tube machine, the rotary coptube spindle f and endless paste-distributing band H, in combination with the throwoff device for the cop-tube, consisting of the spring-pressed rock-lever y, the lever Z, the springpressed throw-off bar it, and its throwoff piece k, all arranged and combined to operate substantially as and for the purpose set forth.

In a cop-tube machine, the following elements in combination, viz a rotary coptube spindle, an endless paste distributing band, and means forholding and releasing it from said spindle, an automatic belt shipping device, and a cop-tube throw-off device, all arranged and connected for automatic operation with a single spring-pressed rod, G, substantially as and for the purpose set forth.

In testimony whereof we have signed our names to this specification, in the presence of two subscribing witnesses, on this 2d day of July, A. D. 1887.
